Sorry to hear about your cancer and fatigue. I’ve been in treatment for recurrent breast cancer, lung NETs and DIPNECH for 5 years now and it’s the meds (Kisqali, Letrozole and octreotide) that all cause the fatigue. The first 2-3 years were the worst. I hope your body adjusts some over time, but I don’t expect to ever have the energy I did before cancer meds. I still enjoy life though. It’s just my new normal with limitations. Best to you.
